Star Screens


Trommel Star Screen |

For facilities that need to process organic material in extremely wet conditions, the Doppstadt SM 720 and 720K trommels can quickly convert into a star screen by simply removing the existing drum and replacing with the star screen insert. Equally as effective as a dedicated standalone star screen, the star screen insert extends the flexibility of an existing SM 720 trammel to match any season and conditions.

Technical Specifications

  • Quickly change from traditional drum to star screen
  • Process material with moisture content of 60% or more
  • Wet material throughput rates more than 50% higher than drum screening
  • Innovative oblong star shape eliminates deck build up
  • Alternate shaft speeds stratify material feed for cleaner oversize and increased production
  • Softer urethane star dramatically extends wear life
